That’s funny actually I never heard anyone else talk about this, but I went through the same thing for about a year. When I was with her it felt great and she made me feel so much better about myself. But I also really enjoy being alone and it made me feel like shit and made me question the relationship like “do I actually like her? Do I just like being wanted? Do I even wanna be in a relationship?” But here I am 4 years later and madly in love. So my advice is just wait it out, don’t do anything rash just yet. They’ll be a time where you know for certain what you need to do. Also, you’re young, so in the end if it doesn’t feel right don’t force it.
